ATTACHEKENT FOR VALVE INSIDJES.

mg. My present invention comprises an at- Be it known that l, MAXIMILTANCHARLES Soilwnmnu'r, a citizen of the United-"States tachment adapted tobe directly applied to of America, residing in the borough of MantheValve insides, and which preferably, 111- 60 5 hattan, city, county, andState of New York, though not essentially, utilizes such thread haveinvented certain new and useful lmas'a means for connection to maintainsaid provements in Attachments for Valve lnvalve proper in a positionwherein it is dissides, of which the following is a specificaengagedfrom said sea This attachment tion. pushes down the pin, and therebymoves the 65 This invention relates to valves for pneuvalve proper fromits seat and prevents its inatic tires or the like, and particularly toc0ntact Wlth the seat until the valve inside the working parts orso-called valve insides, 1S ready f r l seltlon 1n the caslng. The andmore specifically to an attachment usem n t a apted for the purpose 1s afnl in connection with th same, simple cap threaded on its interior toengage w the aforesaid thread of the inside.

In the drawings, wherein l have illustrated one form of the invention,-

Figure 1 is an elevation of a valve inside, showing the improvedattachment connected 75 thereto.

Fig. 2 is an enlarged view of Fig. 1, most of the parts being shown indiametrical section.

Fig. 3 is a view of the top of a valve casing. showing the inside inposition.

Fig. 4 is a cross-section on the line 4-42 in Fi 2.

Be erring to the drawings which illustrate one form of the invention,let A indicate the insides as a whole. In the ty e illus trated theinsides comprise a shell having an exterior thread C designed to screwinto the valve casing, a seat D at the bottom adapted to make contactwith the valve proper E and a packing washer 15 adapted to make a tightjoint with the usual ta cred seat G formed on the valve casing H. hovethe seat G and located in a suitable bore is a spring J, the lower endof which presses against the bottom of the bore and the upper end ofwhich engages a collar K formed or carried by the valve pin L to whichthe valve proper E is connected. This construction of valve inside isalready in certain types of valve insides the parts are so constructedthat when the insides are separated from the valve casing (as well aswhen they are in place) the valve proper is urged against its seat byaspring. In any type of inside it is detrimental for the valve proper toremain in contact with its seat up to the time of actual use within thevalve casing, when, of course, such contact is essential. In the typereferred to, however, the "alve proper not only contacts with its seat,but is urged against it with considerable force by its spring, and thiscondition prevails from the time of manufacture up to the time that theconsumer finally places the device in use. The rubber packing of thevalve proper is by this means scored or indented so that it is apt to beleaky when it is finally used. Some difliculty, although to a'much lessdegree, is experienced in the use of the standard valve insides, wherein.the spring does not function to press the valve proper against its seatuntil the device is placed into use, but nevertheless, the mere contactis detrimental, since it may result in a slight curing of the partstogether, or a slight indentation, which will interfere with thetightness of the valve when it finally reaches the tire. Y

Accordingto the present invention I prolltm ' vide a simple andeiiective means for avoiding this contact between the parts, which isapplicable to the inside itself as distinguished from a container forthe valve insides, or the valve casing itself.

In practically all types of valve inside there is provided ascrew-threaded portion at the top, by means of which the valve inside isscrewed into the valve casing, and there is also provided a pin whichprojects beyond the screw-threaded portion designed eventually to ec meth deflating means known and is used for an illustration of a type inwhich there is constant pressure of the valve proper E against the seatll), irrespective ofwhether or not the device is in position in thecasing. The present'device is, however, applicable to other forms thanthat shown, although it is of special utility in connection with thetype illustrated.

According to the present invention, ll provide a means for engaging thevalve inside and also the pin L, whereby to di lace the in downwardly,thereby moving t e valve proper l3 from its seat. While this maybeaccomplished in various ways, the preferred 'fornris' that shown whereinI provide a the pin extends far enough beyondthe' endv of t e shell ofthe valve insides tobe en: gaged by the cap M without the latterprojecting into the valve inside. However, if the pin is shorter, thecap M may be provided with a depression or the like which will insuresufiicient contact to accomplish the purposes mentioned.

The cap M may be variously formed, and there may be substituted. for itany means for engaging the shell of the valve inside and the pin L tohold the latter depressed.

The device is also useful in connection with the standard inside toinsure that the valve proper does not contact with its seat before beingplaced into use.

It will, of course be understood that the cap or its equivalent shouldbe applied to the valve inside as soon as the latter is manufactured,and remain in position until the consumer desires to apply it to thevalvecasmg, whereupon the attachment is removed and thrown away ifdesired. The cap may be very cheaply constructed of thin sheet metalwith a rolled thread.

While I have shown and described one that I do not wish to be limitedthereto, since various changes may be made therein vwithout departingfrom the spirit of theinvention.

What I claim is l. The combination with a valve inside having a seat anda valve proper, of means carried by the valve inside for holding thevalve proper in a position in which it is'disengaged from its seat. r

2. The combination with a valve inside having a seat and a valve proper,of means carried by the valve inside for holding the valve proper in aposition in which it is disengaged from its scat, said means comprisinga device engaging a screw-thread on the valve inside.

3. The combination with a valve inside having a seat and a valve proper,of means carried by the valve inside for holding the valve proper in aposition in which it is disengaged from its seat, said means comprisinga screw-threaded cap engaging a screw-thread on the valve inside.

4. The combination with, a valve inside having a seat and a valveproper, a spring carried by said inside, a pin connected with the valveproper against which said spring acts, and a member engaging the valveinside and said pin.

In witness whereof, I have hereunto signed my name.
